It's hilarious seeing the sheeple here simply blast Google Photos. Let me guess 95% of the complainers about Google Photos have never even tried the product or service. It's a good one. It's simply disturbing to me how so closed minded some people can be to complain about something they don't even understand.
1. For photo editing and stuff, it does offer some neat features especially if you are on the Android side, but I prefer iOS Photos app for doing markups/annotation. For on device photo management, without a doubt I go with iOS' app.
2. From a sharing perspective, Photos is cross platform. It makes sharing photos with after a family vacation, friends vacation, etc super easy. Most important, someone doesn't even need a phone and can access via web if they wanted to.
3. The unlimited backup feature was neat while it existed from 2015 - 2021. I know our photos are scanned for AI learning, but I used those years to backup basically all my photos from 2003 when I got my first digital camera all the way through present day. That's nice to have, and there's NO WAY iCloud would've been affordable for the amount of data I've put on there.
For those of you who think Google Photos is unsafe, it's not. If you value privacy, then don't use it, but I wouldn't use ANY cloud photo service including iCloud, although the latest Advanced Data Protection may add a lot of privacy benefits for those who are on the fence.
